“…Although patients may agree to home health care at the time of hospital discharge or accept a referral for other reasons, it is possible that once at home, they choose to forgo the care. Patients could believe that additional services are unnecessary or that home health services are low value, or they could prefer not to have health care practitioners in their home …”

Key Points Question How often do Medicare patients referred to home health care at hospital discharge receive a home health care visit, and are there disparities? Findings In this cross-sectional study of Medicare beneficiaries in 2016, only 54.0% of patients discharged from the hospital with a home health care referral received home health care services within 14 days of discharge. This rate was even lower among Black and Hispanic patients, those who were dually enrolled in both Medicare and Medicaid, and patients who lived in high-poverty, high-unemployment zip codes. Meaning These findings suggest that patients may face important differential barriers in access to home health care.

Elastic Coulomb electron-ion and ion-ion collisiors in electron ~ams and piasra are studied.The use of low charged, light ions for cooling multiply charge ions zn Electron Beam Ion Source (EBIS) [ 1],Electron Ring Ion Source (ERIS) [2] and Sletron Cyclotron Resonance Ion Source (ECRIS) [3,4] is substantiated.i.Introduction.EBIS, EBIT[5] and ECRIS are succes-si~lly used now for ion production. Recently, a new type of ion source (ERIS) was proposed. A lot of articles and reviews were devoted to the problem of ionization and charge exc~ processes last yeas [6].The elastic Coulomb collisions of charge particles in plasma have been studied well in connection with the thermontr_&ear fusion arches.lt is descri~=d in the textbooks now [7,8]. S~t these p~are not yet taken into accost in the calculations of ion appearance and accLmulation in ion sources.The elastic Coulomb colli-~ons can explain some o observed effects and show the way to incre~ the ion sources effectiveness.2.General equatioas. Elastic scattering of an electron beam on stored ions, residual gas or solid target is a cause of tran~,er~ team dime]qsion -and mittance increase [3,9]. The ions receive an additional momentum in the Coulomb collisions. The energy increase of ions with charge state Z and mass ~ is determined from the eqtmtion [3]: dE/dt=reaZ~NemC2A/ae3~ , ( 1 ) where ~--Ve/C; m,re,ve are the mass, the clae~ical radius and the velocity of electrons;c is the velocity of light;a-P~S s~l] halfdimention of electron beam;A=10-20 is so called Coulomb lo~thm.In the electron team ions are p~e d as the ~tlt of electron impact ionization of the neutral at~s or molecules in the ~.3m.The energy of a single charged ion eq;~],~ to the electric field potential in the place of ion appearance and as a ~e is much more than the energy of a neutral. The ions ~ in the potential well of the ~eand ~j i n to oscillate.They t~dergo f t~t~r ionization and inc~ase the c~rge and the energy.

It was shown, that in this case the ions were o~tside the team most of the time, they don't de~end much on the electron component and we consider these ions to be the lost particles [ 1I].
