MORTALITY RATES IN PATIENTS WITH BURNS—A Report of Experience at San Francisco City and County Hospital, 1943-1956

A review was made of the cases of 93 patients with burns covering more than 20 per cent of the body surface who were treated at the San Francisco City and County Hospital, University of California Service, between 1943 and 1956.The mortality rate increased from 40 per cent during 1943-1947 to 69 per cent during 1952-1956. A significant change in survival time was noted: During 1943-1947, 69 per cent of the deaths occurred within 48 hours of admission; during 1952-1956, only 19 per cent of the deaths occurred within the first 48 hours. In the period 1943-1947 the majority of deaths resulted from shock in the immediate post-burn period; in the later years of the study the major cause of death was infection.No patient more than 50 years of age who had burns of more than 25 per cent of the body surface survived. Only one patient with burns involving more than 45 per cent survived.No patient who had a blood culture positive for bacteria survived. The use of antibiotics had no effect on the incidence of infection. Elderly patients, children and alcoholics were less able to resist the effects of infection.The lowest mortality rate was in the age group of 15 through 35 years.     

MODERN TREATMENT OF PLACENTA PREVIA—A Study of 234 Cases

Study was made of 234 cases of placenta previa occurring in 48,752 deliveries at one hospital during the period 1947-1956. There was no maternal mortality. The uncorrected fetal mortality rate for all weight groups was 21.4 per cent. The rate varied from 88 per cent in babies under 1,500 grams to 5.7 per cent in babies over 2,500 grams. Initial conservative management to permit gestation to continue as close to term as possible is advisable.Ultimate termination of the pregnancy by cesarean section under spinal anesthesia gave the best results. The incidence of transverse and breech presentations in association with placenta previa was inordinately high. A progressive trend toward more conservative treatment of placenta previa was noted in the present series, with a concomitant reduction in fetal mortality rate.

CIRRHOSIS OF THE LIVER—Clinical Course in 2,377 Patients at San Francisco General Hospital

The records of 2,377 patients with Laennec''s cirrhosis were reviewed for the period 1947-1957. The chief presenting symptom was ascites in 46 per cent, bleeding in 23 per cent, coma in 18 per cent, jaundice in 9 per cent, and both jaundice and ascites in 4 per cent. Nearly half of the patients died during the period under study—one-third from hepatic failure, one-third from gastrointestinal bleeding, and one-third from other causes, most of which were related to alcoholism.Massive gastrointestinal bleeding occurred in 21 per cent of the patients at some time in their clinical course, and in the 10 per cent of these in whom ulcer was demonstrated, one-fifth died as a result of the hemorrhage. Of those presumed to be bleeding from esophageal varices, 64 per cent died at the first hemorrhage and 10 per cent at subsequent hemorrhages; 85 per cent of all those who bled from varices were dead at the end of one year, and 91 per cent were dead at the end of three years.The survival curve of a group of patients who bled once and were good operative risks but had received no operative treatment was compared to the survival curve for entire group who survived the first hemorrhage. The three-year survival in the good risk group was 47 per cent; for the group as a whole it was 30 per cent. The difference in mortality rate was primarily due to an increased number of deaths from hepatic failure in the combined group, whereas 60 per cent of the good risk group died of recurrent gastrointestinal hemorrhage.As 86 per cent of those who were to die of gastrointestinal bleeding did so at the first hemorrhage, it was concluded that any decided improvement in the salvage rate achievable by operation must come from some means of diagnostic forecast of the likelihood of bleeding, with resort to prophylactic operation in such cases.     

PERFORATED PEPTIC ULCER—Selective Gastric Resection in Emergency Treatment

In a series of 240 cases of perforated peptic ulcer prior to 1952 there was a total mortality of 17 per cent. This included cases treated conservatively as a planned procedure or because of other morbid conditions and undiagnosed cases, all ending in death.In cases treated by simple suture, mortality was 2.6 per cent for patients under 50 years of age and 17 per cent for those over 50, the rate rising very steeply with each decade over 50.From 1953 through 1959 selective gastric resection was carried out, the operation being done in all cases of perforated gastric ulcers, of chronic duodenal ulcers and of perforations associated with hemorrhage.During this period 303 perforated ulcers were treated, with a mortality of 15.5 per cent. Patients with associated morbid conditions and those admitted moribund and died, or died undiagnosed were again included.In this series also the mortality increased steeply from age 50 onward.Gastric resection was carried out in 148 cases of perforated peptic ulcer with a mortality of 6 per cent. In 105 cases under 60 years of age there were no deaths but in those over 60 the mortality rate was 21.8 per cent. Results in the patients who had resection, as determined after three years of observation, compared favorably with the results in patients who were treated by suture.The mortality of perforated ulcers in females was higher than in males.Emergency gastric resection has a definite place in the treatment of perforated peptic ulcer.     

Duration of Last Attack in 998 Fatal Cases of Coronary Artery Disease and its Relation to Possible Cardiac Resuscitation

All the deaths attributed to coronary artery disease and occurring in Belfast during one year were studied.The frequency distributions of the cases by interval of time between onset of the last attack and death are given for those not admitted to hospital, for those admitted to hospital, and for those already in hospital for some other cause of illness.Sixty per cent. of all the deaths occurred outside hospital. This indicates that the problem of cardiac resuscitation in coronary artery disease is to a considerable extent an extra-hospital one.Twenty-seven per cent. of the men and 22% of the women died within 15 minutes, but the median period of survival was 3 hours 30 minutes for men and 6 hours 18 minutes for women.The median time interval from the onset of the attack to sending for medical aid was 1 hour 17 minutes for men and 1 hour 6 minutes for women, and from summoning medical aid to sending for the ambulance 59 minutes for men and 1 hour 26 minutes for women. Ninety-six per cent. of the ambulance journeys to the patient were accomplished in less than 20 minutes.It was found among men, but not among women, that the duration of survival tended to be longer in older patients and in second or subsequent attacks.Of the 596 who did not gain admission to hospital 229 (23% of all the 998 patients) were known to have survived for more than half an hour after the onset of the fatal attack; 182 (18%) survived for more than one hour; and 143 (14%) survived for more than two hours. It is among these that there would appear to be special scope for the cardiac ambulance, providing that medical aid is sought and the ambulance is summoned without delay.     

Survival in acute myocardial infarction; factors observed in 318 patients

Factors influencing survival in a group of 318 cases of acute myocardial infarction were analyzed. The mortality rate for the entire series was 41 per cent. Among the men it was 39.5 per cent; among women, 44.4 per cent. The mortality rate increased with the age of the patient. Twenty-six per cent of all deaths occurred within the first 24 hours, 44 per cent within 72 hours, and 71 per cent within the first week following hospital admission. Increased mortality rate was associated with previous history of congestive failure, myocardial infarction, hypertension or cardiomegaly. As to circumstances immediately preceding an infarction, the only ones that seemed to be related to a high mortality rate were hemorrhage and the postoperative state. Not only the presence but the degree of shock, congestive failure, cyanosis and dyspnea adversely influenced chances for survival. Duration, location, radiation and number of attacks of pain did not appear to be associated with extraordinary mortality rates. Anterior was slightly more common than posterior infarctions, and the mortality rate was much higher. Thromboembolic complications and certain disorders of rhythm and of conduction definitely worsen prognosis. Comparison of average mortality data as reported in different studies on acute myocardial infarction is improper and misleading because of the great differences between the kinds of patients included in various series reported upon. A standard method of grading the severity of acute myocardial infarction would help toward sounder comparisons.     

Autopsy in California

From information complied from death certificates registered in 1952 and 1962 an examination was made of California''s autopsy performance and the characteristics of deaths in which autopsy was done. The data indicated that California had an overall autopsy rate of 37 per cent of total deaths in 1962, probably higher than any other state. In the decade reviewed, there was a 62 per cent absolute increase in autopsies and a 7 per cent increase relative to total deaths.Substantial increases in the proportion of deaths in which autopsy was done were found for physician-certified deaths in both metropolitan and nonmetropolitan counties and for coroner-certified deaths in nonmetropolitan counties. For all but two of forty-five selected natural causes of death there were increases in the proportion of deaths in which autopsy was done.Seventy per cent of deaths occurred in some type of facility. About one-half of all deaths occurred in general hospitals, and autopsy was done in 42 per cent of such cases.The dual factors of a high autopsy rate and overrepresentation of deaths brought to autopsy in white males, ages 35-64, support the validity of a reported decline in California''s death rate for arteriosclerotic heart disease.     

Medical technicians; the present need and training in California

A maternal welfare committee was founded in 1947 by representatives of nine hospitals in San Diego County, with the purpose of inquiring into all deaths involving maternity in order to reduce maternal mortality. At open meetings cases of such death are reviewed and a vote is taken on whether the death was preventable. Deaths of newborn children are also investigated for preventable factors. From 1947 to 1952 the maternal mortality rate has declined among residents of the county from 7.3 per the thousand live births to 2.7. It is believed that the emphasis placed on high standards of prenatal and postpartum care by the committee's observations has greatly aided in securing this improvement.

Mortality associated with HIV-1 infection over five years in a rural Ugandan population: cohort study.

OBJECTIVE: To assess the impact of HIV-1 infection on mortality over five years in a rural Ugandan population. DESIGN: Longitudinal cohort study followed up annually by a house to house census and medical survey. SETTING: Rural population in south west Uganda. SUBJECTS: About 10,000 people from 15 villages who were enrolled in 1989-90 or later. MAIN OUTCOME MEASURES: Number of deaths from all causes, death rates, mortality fraction attributable to HIV-1 infection. RESULTS: Of 9777 people resident in the study area in 1989-90, 8833 (90%) had an unambiguous result on testing for HIV-1 antibody; throughout the period of follow up adult seroprevalence was about 8%. During 35,083 person years of follow up, 459 deaths occurred, 273 in seronegative subjects and 186 in seropositive subjects, corresponding to standardised death rates of 8.1 and 129.3 per 1000 person years. Standardised death rates for adults were 10.4 (95% confidence interval 9.0 to 11.8) and 114.0 (93.2 to 134.8) per 1000 person years respectively. The mortality fraction attributable to HIV-1 infection was 41% for adults and was in excess of 70% for men aged 25-44 and women aged 20-44 years. Median survival from time of enrollment was less than three years in subjects aged 55 years or more who were infected with HIV-1. Life expectancy from birth in the total population resident at any time was estimated to be 42.5 years (41.4 years in men; 43.5 years in women), which compares with 58.3 years (56.5 years in men; 60.5 years in women) in people known to be seronegative. CONCLUSIONS: These data confirm that in a rural African population HIV-1 infection is associated with high death rates and a substantial reduction in life expectancy.     

MATERNAL AND PERINATAL DEATHS IN CALIFORNIA

In a 29-month period, 151 of 373 deaths of California women occurring during or within 90 days of termination of pregnancy were studied jointly by the California Medical Association and the California State Department of Public Health. Twenty-two per cent of the deaths reviewed were considered unavoidable. In 74 per cent, one or more avoidable factors were identified. Avoidable factors could not be identified in 4 per cent of the cases.Thirty-three per cent of the cases considered to have avoidable factors were attributed to be solely the responsibility of the attending physician. Inadequate hospital facilities were held responsible in less than 1 per cent of deaths, while responsibility in 26 per cent of the deaths was laid directly to patient error or refusal. In 40 per cent of the avoidable deaths, more than one avoidable factor was identified.Nonobstetric conditions accounted for the greatest proportion of the deaths, followed by hemorrhage, toxemia of pregnancy, sepsis, abortion and ectopic pregnancy.The findings of this study compare closely with those of similar studies in other states, including Minnesota and Massachusetts.     

A retrospective study of 932 second trimester terminations using gemeprost (16,16 dimethyl-trans delta 2 PGE1 methyl ester).

A retrospective study of 932 second trimester terminations between 12-27 weeks gestation was carried out to determine the efficacy of gemeprost for second trimester termination. A single course of 5 x 1 mg gemeprost pessaries was administered every three hours. If abortion had not occurred after the first course of pessaries, a further course of 5 x 1 mg pessaries was administered. Intravenous oxytocin was administered after 36 hours if abortion had not occurred. Eighty per cent and ninety five per cent of patients aborted within 24 and 48 hours respectively. Of the remaining 5 per cent of women, 3 per cent aborted with escalating doses of oxytocin. In the remaining 18 (2 per cent) women, the pregnancies were electively terminated with an alternative method. The median induction-abortion interval was 18.0 hours and 15.0 hours in nulliparous and parous women respectively (P less than 0.0001). The number of pessaries required to induce abortion was not influenced by parity. Significantly more parous women bled more than 500 ml. The incidence of pelvic sepsis (0.1 per cent) and cervical tear (0.1 per cent) was low. Twenty six per cent of women had diarrhoea and 23 per cent vomited following administration of prostaglandin. This study confirmed the efficacy of gemeprost for second trimester termination of pregnancy. This method of termination is safe, non-invasive, simple and has a low complication rate.     

Secular decline in mortality from coronary heart disease in adults with diabetes mellitus: cohort study

Objective To examine trends in fatal coronary heart disease in adults with and without diabetes.Design Cohort study.Setting Two surveys of the Nord-Trøndelag health study (HUNT), a population based study in Norway.Participants 74 914 men and women from the first survey (1984-6) and 64 829 from the second survey (1995-7).Main outcome measure Age specific mortality from coronary heart disease among adults with and without diabetes during two consecutive nine year follow-up periods.Results A total of 2623 men and 1583 women died from coronary heart disease. Mortality rates were substantially lower during the most recent follow-up period: among men aged 70-79 without diabetes, deaths per 1000 person years declined from 16.38 to 8.79 (reduction 48%, 95% confidence interval 39% to 55%) and among women aged 70-79 from 6.84 to 2.68 (62%, 52% to 70%). Among the same age group with diabetes, deaths per 1000 person years in men declined from 38.97 to 17.89 (54%, 32% to 69%) and in women from 28.15 to 11.83 (59%, 37% to 73%). The reduction was more noticeable in age groups younger than 70 at baseline, and less pronounced among people aged 80 or more. Mortality from coronary heart disease was more than twofold higher in people with than without diabetes, with a slightly stronger association in women. The difference in mortality by diabetes status remained almost unchanged from the first to the second survey.Conclusion The strong general reduction in mortality rates from coronary heart disease from the first to the second follow-up period also benefited people with diabetes, but the more than twofold higher mortality from coronary heart disease associated with diabetes persisted over time.     

Surgical Treatment of Mitral Insufficiency

Sixty-four patients with pure mitral insufficiency were operated upon. Thirty of them had torn chordae tendineae. It was possible to repair the mitral valve in 57 patients and there were five operative deaths. One patient had a femoral artery embolus and another had a cerebral embolus. The incidence of peripheral embolization was 4 per cent compared with 40 per cent reported for ball valve replacement.Forty-eight of the 57 patients with repair (84 per cent) were living and well with at most a grade II/VI apical systolic murmur up to seven and a half years after operation. There has been no evidence of recurrence in these patients.In approximately 90 per cent of patients with pure mitral insufficiency, repair should be performed. When feasible, repair is more satisfactory than valvular replacement, with not only excellent long-term results, but far less morbidity than is reported with ball valve replacement.     

OPERATING ROOM DEATHS—An Analysis of Mortality in a Veterans Administration Hospital Over a Ten-Year Period

A study of operating room and recovery room deaths which occurred during a ten-year period from 1948 through 1957 at one hospital revealed that there were 59 deaths associated with 57,132 surgical procedures.Factors which directly influenced the rate of operating room and recovery room death were the age of the patient and the length of operating time. Seventy-five per cent of the deaths occurred in cases in which the operation took longer than one hour. Combined anesthesia techniques may have indirectly contributed to death in some cases.Complications of operation requiring another surgical procedure sometimes occur. In this series, reoperation proved to be more hazardous in terms of mortality rate than did single operations. This is not surprising for most complications occur in the poorer risk patients.The operating room death rate steadily increased during the ten-year period studied. This increasing death rate can largely be attributed to the more intricate operations which are being done on poorer risk patients. The use of the curariform drugs had no influence on the increasing death rate.

Sex differentials in perinatal mortality in china and Finland

Abstract

This study describes patterns of sex differentials in perinatal mortality in China and Finland. The analysis is based on three population‐based one‐year birth cohorts, one from Qingdao, China, in 1992 and two from Northern Finland in 1966 and 1985–86, comprised of 9,219, 11,422 and 9,207 singletons with at least 28 gestational weeks and 1000 g in birthweight, respectively. Both Finnish cohorts had an excess of male over female perinatal deaths, but in the Chinese cohort girls were more likely to die than boys. The adjusted odds ratio (OR) of perinatal mortality for boys was 1.31 (95 per cent confidence interval [CI] 0.98,1.78) and 1.57 (95 per cent CI 0.89, 2.78) in the Finnish 1966 and 1985–86 cohorts, respectively, and 0.82 (95 per cent CI 0.55,1.20) in the Chinese cohort. The corresponding figure for stillbirths in the Chinese was 0.57 (95 per cent CI 0.33, 0.98), which could explain the total excess of female deaths during the perinatal period. Our results suggest that the role of different social and cultural environments on the existing sex differentials in perinatal mortality between the countries needs further evaluation.     

Terminal symptoms in children dying suddenly and unexpectedly at home. Preliminary report of the DHSS multicentre study of postneonatal mortality.

Terminal symptoms in 145 children who died suddenly and unexpectedly at home were investigated and compared with symptoms in 154 control children. Eighty-five (59%) of the children who died had had terminal symptoms, which in 69 cases (48%) appeared to have been major. Non-specific symptoms were especially common among the children who died. Symptoms were often present for several days before death. Only 12 of the 69 children who died with major symptoms had been seen by a doctor within 24 hours before death. We conclude that many deaths in young children might be prevented if doctors and parents were more aware of the importance of non-specific symptoms as markers of life-threatening illness.     

SUPRACONDYLAR AMPUTATION IN THE AGED

Of 105 consecutive supracondylar amputations done at the San Diego County General Hospital during the five-year period, 1953-58, 88 were in patients more than 60 years of age. Occlusive arterial disease was the reason for operation in 85 of the 88 cases.Presenting complaints at the time of amputation were gangrene in 45 cases, pre-gangrene associated with severe pain in 34. Acute arterial occlusion as a cause of thigh amputation was infrequent.The average age of patients requiring thigh amputation from complications of arteriosclerosis obliterans was 78.3 years; for those with diabetic arteriosclerosis or embolism it was about seven and a half years less.Supracondylar amputation was considered the procedure of choice in the elderly debilitated patients with far-advanced occlusive diffuse arteriosclerosis, complicated by gangrene, ulcer and infection of the toes or feet. Sympathectomy and direct arterial operation if done early in the course of the disease may postpone or prevent subsequent amputation.The surgical mortality rate (first two weeks) for supracondylar amputation was 12.5 per cent. More than two-thirds of the deaths were due to bronchopneumonia.
