title: [Comparison of development and mortality under domestic or institutional care with and without medical rehabilitation : The Hannover morbidity and mortality long-term care study].
abstract: OBJECTIVE
  Empirical data, representative of the total population, are necessary for medico-actuarial risk calculations. Our study compares mortalities of long-term care (LTC) patients who are covered by statutory health insurance with regard to age and distribution of care levels when in home or institutional care with a special focus on whether rehabilitative care was performed.
  
  
  METHODS
  The data of 88,575 LTC patients were analyzed longitudinally for 10 years, using routine data analyses on the files of the German Federal Health Insurance fund (average observation period 2.5 years, a total of 221,625 observation years). The numbers of LTC patients and their care levels while in home or institutional care were calculated, as were any changes to another care level or discontinuation of LTC benefits (as a result of the need for care falling below the eligibility criteria for care leveI or to death) during 1-10 years after the onset of LTC, always with respect to whether rehabilitative care had taken place or not. For the evaluation of care factors an indicator was developed.
  
  
  RESULTS
  Total mortality was found to decline and reactivation to increase considerably for LTC patients after rehabilitation, basically irrespective of their age or care level and in home or institutional care settings as well. Ten years after the onset of care, 30.7 % of the patients with rehabilitation were still in nursing care, 9.8 % were reactivated and 59.5 % deceased. In contrast, only 9.2 % were still in nursing care, 3.7 % reactivated and 87.1 % deceased without rehabilitation. These results are irrespective of age distribution, care level, and residence in home or institutional care settings. The care status of patients, measured by the percentage in reactivation, care level I-III, and death, substantially depends on age at onset and care level and in addition on rehabilitative procedures. Hypotheses for further research are outlined.
  
  
  CONCLUSIONS
  Rehabilitation has a clear-cut potential for life extension as well as reducing or detaining long-term care if applied to (LTC) patients. The group of rehabilitated LTC patients has a comparatively higher degree of reducing or resolving LTC up to a complete reactivation or prolonging of life in spite of care needed. A successful rehabilitative effect occurs over all age groups and all care levels during home care considerably as well as during institutional care to a lower extent. Differentiation between the age at onset of LTC, care level, and first year and follow-up mortalities is recommended as well as between rehabilitated and nonrehabilitated care patients when undertaking medico-actuarial calculations.
